HP XP7 RAID Manager Reference Guide (T1610-96064)

DescriptionOption
If you specify -tse_ldev_id option, the volume is the same as the volume used by FlashCopy
SE. When using -tse_ldev_id option, you must create the virtual volumes in Thin
Provisioning Z. Examples:
• -ldev_id 200
• -tse_ldev_id 400
Specifies the capacity. The size can be specified in bytes or LBAs. When specifying
bytes, the unit is t/T (terabyte), g/G (gigabyte), m/M (megabyte), or k/K (kilobyte). If
this option is omitted, block (512KB) is used.
-capacity <size>
When specifying byte, note the following:
• There is no size correction.
• If the capacity of LDEVs that are created by GUI and by CLI are the same, a copy
pair might not be created. To create a pair with an LDEV that was created by GUI,
create the LDEV by specifying LBA.
Example of specification:
1GB (gigabyte) is:
-capacity 1G, -capacity 1g, -capacity 1024M, -capacity 1024m, -capacity 1048576K,
-capacity 1048576k, -capacity 2097152
In the case of volumes other than OPEN-V, more free space than the capacity that was
actually specified is required. For details, see the HP XP7 Provisioning for Open Systems
User Guide.
When you specify "all" instead of digits to create an OPEN-V LDEV and no LDEV has
been created in the specified parity group* or the external volume group, the system
allocates all empty space for the LDEV. If the empty space is larger than the maximum
capacity of an LDEV, the system creates the LDEV with the maximum capacity and leaves
the rest of the space as an empty space.
*: "all" cannot be specified depending on the combination of the drive type and drive
level because of the LDEV control area allocation, and so on. In this case specify byte
or LBA.
Specifies capacity. Corrects the size as well as GUI for the specified capacity. The
capacity can be specified in bytes or blocks. When specifying byte, the unit is t/T
(terabyte), g/G (gigabyte), m/M (megabyte), or k/K (kilobyte).
-offset_capacity <size>
Specifies the size in cylinder unit. When specifying, the unit is t/T (teracylinder), g/G
(gigacylinder), m/M (megacylinder), or k/K (kilocylinder). Cylinder is applied if you do
not specify the unit.
-cylinder <size>
When an open-systems emulation type is specified, this option cannot be specified.
Specifies the Location (the starting point of the LDEV to be created in the parity
group/external volume group). If this specification is omitted, create a LDEV and close
up in the free space.
[-location <lba>]
Specifies the emulation type. For example:
• OPEN-V
If this specification is omitted, OPEN-V is specified.
[-emulation <emulation
type> ]
If this specification is omitted when the virtual volume is crated, the following emulation
type is specified.
• OPEN-V: Thin Provisioning or Smart Tiers
• 3390-A: Thin Provisioning Z or Smart Tiers Z
The values that can be specified for <emulation type> are:
• OPEN-3, OPEN-8, OPEN-9, OPEN-E, OPEN-L, OPEN-V
• 3380-3, 3380-3A, 3380-3B, 3380-3C
• 3390-1, 3390-2, 3390-3, 3390-A, 3390-3A, 3390-3B, 3390-3C, 3390-3R, 3390-9,
3390-9A, 3390-9B, 3390-9C, 3390-L, 3390-LA, 3390-LB, 3390-LC, 3390-M,
3390-MA, 3390-MB, 3390-MC, 3390-V
